MOSREF Shell Shock..

Work has been quiet but steady on MOSREF, with some very intense work on restoring the "proxy" command and improving the Console's resilience against malfunctioning Drones and noise. All of the functionality from MOSREF 2.0b3 has been restored, with the sole exception of the "scan" command; it took me longer than expected, but a very subtle bug in vm/os.c was locking up Drones when a specific sequence of proxy sessions was introduced. I also discovered an interesting hiccup in GCC when compiling vm/format.c with -Os or -O3. Until I get a chance to examine the optimizations involved, the Makefile will default to compiling with the more conservative -O2 optimization flags.
